Introduction to tourism.

I think the three basic elements of tourism activities are: travel agency, hotel and transportation. The three are the three pillars of modern tourism activities, among which the travel agency industry is in the core position, the link between tourism demand and tourism supply, and the vanguard of tourism activities;

Hotel industry is the pillar industry of tourism activities, an important channel for tourism income generation, a material basis for tourism development and an important channel for attracting employment, which helps to strengthen the social and cultural functions of tourism;

Tourism traffic is a prerequisite for the emergence and development of tourism, which helps to promote the rise and development of tourist areas and is an important source of stable economic income for tourism.

The two are closely related, and the steady development has promoted the sustainable development of tourism, a "smokeless industry".
